Experimental study of coupled quantum billiards with integrable and chaotic classical dynamics and test of a special Rosenzweig-Porter model
Xiaodong Zhang, Jiongning Che, Barbara Dietz
We report on the experimental study of the spectral properties of quantum systems consisting of two quantum billiards (QBs), one with chaotic, the other one with integrable classic…

Experimental study of the distributions of off-diagonal scattering-matrix elements of quantum graphs with symplectic symmetry
Jiongning Che, Nils Gluth, Simon Köhnes +2
We report on experimental studies of the distribution of the off-diagonal elements of the scattering matrix of open microwave networks with symplectic symmetry and a chaotic wave d…

Exact Results for the Ericson Transition in Stochastic Quantum Scattering and Experimental Validation
Simon Köhnes, Jiongning Che, Barbara Dietz +1
At lower energies, the resonances in scattering experiments are often isolated. The crucial parameter is the ratio of average resonance width and average mean level spacing. Toward…
